Nortec OnLine GSTC - Manual (Page 5)

Installation | 1
Overview
The NORTEC OnLine Option provides a web-based remote monitoring capability to equipped
GSTC or SETC series humidifiers. The NORTEC OnLine option operates in conjunction with a
centralized server based at NORTEC's facilities. This server allows the user to monitor and
control various aspects of the humidifier operation. If a fault or service warning is detected the
NORTEC server will send an email response to three user-specified personnel. NORTEC OnLine
also provides NORTEC with the ability to diagnose the humidifier's performance remotely,
ensuring quick response to customer inquiries.
NORTEC OnLine provides the advantages of immediate notification and quick diagnosis of
humidifier fault conditions, should they arise. NORTEC OnLine also provides a user-friendly BMS-
like interface, even when a dedicated Building Management System is not available or
unfeasible. All that is required for NORTEC OnLine’s operation is either an internet connection,
an external phone line or a wireless network connection.
Offerings
NORTEC OnLine supports three types of connections to the internet: Ethernet, Dialup modem,
and GPRS modem. Both static IP and DHCP addressing is available for ethernet connections.
Simply specify at the time of order, which type of connection type would be preferable and any
details that may apply (refer to the configuration form at the back of the manual). Once in the
field, a user can differentiate between the different connection types by inspecting a tag present
on the OnLine module. This identifier tag will provide details such as connection type and part
number information.
For sites where LAN/internet connections are available, the OnLine module may be plugged into
the network through an ethernet port present on the control board. NORTEC OnLine is capable
of operating with either a Static IP address or a Dynamic IP address. Wide area network (WAN)
port 5222 must be opened to TCP traffic for the units to communicate with the NORTEC OnLine
Service.
The NORTEC OnLine module also comes equipped with a serial port which allows a dial-up
modem or a wireless GPRS modem to be connected. All the necessary programming for the
connection details will be pre-programmed at the factory.
Humidifier Wiring
It is possible to network up to a maximum of 8 units to a single NORTEC OnLine module. This
OnLine module is located internally to the GSTC or SETC unit. When multiple humidifiers are
present, only a single module is required and will be installed inside a 'lead' unit, which can be
specified by the user. Since each unit is separately addressed, it is possible to monitor and
control each unit independently.
